What is Granite?

Granite is an intrusive igneous rock which is widely distributed throughout Earth’s crust at a range of depths up to 31 mi (50 km). Granite’s characteristic grainy structure and strength is the result of many individual crystalline structures which form tightly together as magma slowly cools within large, deeply buried rock bodies known as plutons. True granite contains 20-60% quartz as well as both plagioclase and alkali feldspars of which the former may not exceed general balance.

Extraction and Block Selection

Extraction (more commonly referred to as quarrying) consists of removing blocks or pieces of stone from an identified and unearthed geologic deposit. Differences in the particular quarrying techniques used often stems from variations in the physical properties of the deposit itself—such as density, fracturing/bedding planes, and depth.

Block cutting

The first step of the process is a primary cutting or shaping of the material. This is typically accomplished for granite using a diamond wire-saw. When operating a circular or diamond wire saw, a continuous tream of water over the saw is required in order to dissipate heat generated by the process; sufficiently-elevated temperature can cause major machine and material damage.

Grinding & epoxy application

Grinding is done in a grinding machine with multiples heads attached to diamond abrasives of different densities to achieve an even surface finish. Again water is used in this process to minimise heat created from friction.

Epoxy resin is applied to fill all of the pits and micro-fissures that are occuring naturally and also to ensure the the stone is hardened further.

Polishing

This is the final step before the granite slabs are ready. This step is done to remove any excess resin on top of the granite surface as well as smoothen the surface finish.

The slabs are processed with special silicon carbide abrasives in a polishing machine and goes through a process of differing hardness and pressure with 21 abrasives to ensure a smooth surface finish and a mirror like shine.
